Google browser sync
Although I was moaning about google's gmail not being able to have two windows at the same time. The guys of google are helping me to sync between home and work in an other way: the Google browser sync option in firefox. It works brilliantly and all of my search, cookies and bookmarks are always in sync.As with all services of Google it is still in BETA. (everything seems to be BETA nowadays, but that's an other story)
